Application filed April 1,

To all whom it may concern Be it known that I, JOHN Counrnnn, a citizen of the United States, residing at Dewey, in the county of Washington, and State of Oklahoma, have invented certain new and useful Improvements in Rim Tools, of which the following is a specification.

The present invention relates to atool constructed to operate in conjunction with the rim shown in my application filed of even date.

An object of the invention is to provide a tool whereby the rim may be easily contracted or expanded. The tool embodies a very simple and efficient construction which may be manufactured at a comparatively low cost and which will be efiicient in operation, and well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the desription progresses, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a plan view showing my invention,

Figure 2 is a section through the tool, and

Figures 3 and 4: are fragmentary sections therethrough showing the tool in different positions.

Referring to the drawing in detail it will be seen that the tool includes frames A and B. The frame A is formed with the two elongated side members 1 and the intermediately disposed transverse member 2. The bar 3 is rotatable on the transverse member 2 by means of apertured ears 4 receiving the member 2. The frame B includes the two elongated side members 5 and cross member 6 at one end. The frame A is pivoted to the frame B adjacent the latter cross member 6 as indicated at 7 In order to understand the operation of this invention it is necessary to refer to my application for rims filed of even date wherein it will be seen that the rim is of the split type being provided with transversely extending grooves 9 and 10 and a latch 11 is pivoted to extend over the groove 9. These grooves are situated one on each side of the split 12. One face of the groove 10 is notched or round d, th s f e s fur 1924. Serial No. 703,515.

To operate the tool the same is placed in the position shown in Figure 2 with the frame disposed at an angle and the cross member 6 positioned in groove 9 and the cross member 2 positioned in groove 10 at which time the bar 3 is also placed in the groove 10 to force the member 2 in engage ment with the curved or notched face of the groove 10 so that the same cannot be pulled out of the groove until the filler block or bar 8 is rotated around the member 2 out of the groove 10. The cross member 6 is held within the groove 9 by pivot- .ing the latch 11 over'the groove as is indicated in Figure 2. With the tool positioned and associated with the rim as illustrated in Figure 2, the frame B is moved alongside of frame A to the position shown in Figure 3 thus causing the separation of the split in the ring after which both frames may be swung to the position shown in Figure 4: so that the ends of the rim overlap each other and thus is contracted.

It is thought that the construction and operation of this invention will now be clearly understood without a more detail description. It is desired, however, to point out the numerous changes within the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A tool of the class described including a pair of frames one pivoted to the other intermediate its end and each provided with cross members for engagement with grooves provided in a rim. one cross member being provided with a filler block rotatable thereabout.

2. A rim tool of the class described ineluding a pair of frames, one frame including a pair of parallel side members and an end cross member, the other frame including a pair of parallel Side members an an intermediately disposed cross member, the In testimony whereof I affiX my signature last mentioned frame being pivoted at its in presence of two Witnesses.
